As shown in fig. 1 to 3, in an embodiment of the present invention, the motor 200 can achieve a large-area cooling effect and an energy-saving effect. The motor 200 includes a cooling device 1 and a motor body 210, the cooling device 1 receives a cooling fluid 100 to cool the motor body 210, and the motor 200 is a vacuum motor or a water pump. The coolant 100 is, for example, water. The cooling device 1 comprises a cylindrical housing shell 10, a water inlet 20, a water outlet 30, three water outlet guide strips 40, 40a, two water inlet guide strips 50 and an upper cover 60.
In an embodiment of the present invention, the cylindrical housing 10 is used for housing the motor main body 210, the cylindrical housing 10 includes an annular housing space 11, a top portion 12, an opening 13, an outer wall 14 and an inner wall 15, the cylindrical housing 10 has a long axis direction F, the annular housing space 11 houses the cooling liquid 100, and the annular housing space 11 is located between the outer wall 14 and the inner wall 15. The top 12 includes a top surface 121, and the top surface 121 is the surface facing and contacting the upper cover 60. The motor main body 210 is accommodated in the cylindrical accommodation case 10 through the opening 13. Since the cylindrical housing case 10 surrounds the motor main body 210, the cooling liquid 100 in the annular housing space 11 performs a large area of heat exchange with the motor main body 210 for the purpose of cooling the motor 200.
In an embodiment of the present invention, the water inlet 20 is disposed at the top 12 of the cylindrical housing shell 10 and communicates with the annular accommodating space 11, and the water inlet 20 is used for the cooling liquid 100 to flow into the annular accommodating space 11.
In an embodiment of the present invention, the water outlet 30 is disposed at the top 12 of the cylindrical housing shell 10 and communicated with the annular receiving space 11, and the water outlet 30 is located beside the water inlet 20. The water outlet 30 is used for allowing the cooling liquid 100 after absorbing heat to flow out of the annular accommodating space 11. The water inlet 20 is located at a different level than the water outlet 30, and the water outlet 30 is closer to the top surface 121 than the water inlet 20, that is, the height of the water outlet 30 is higher than the water inlet 20.
In one embodiment of the present invention, three water outlet guide strips 40, 40a surround the inner wall 15 of the cylindrical housing shell 10 and are located near the top 12. One of the water outlet guide bars 40a is disposed at the uppermost portion of the cylindrical housing case 10, and the other two water outlet guide bars 40 are disposed below the water outlet guide bars 40 a. A water outlet guide opening 41 is formed between the two water outlet guide strips 40. Two transversely extending water outlet guide channels 42 are formed between the water outlet guide strip 40a and the two water outlet guide strips 40, and the water outlet guide channels 42 are arc-shaped. One of the outlet guide channels 42 communicates with the outlet guide port 41 and the water outlet 30, and the one of the outlet guide channels 42 is used for guiding the cooling liquid 100 flowing from the outlet guide port 41 to the water outlet 30. However, the design of the water outlet structure of the present invention is not limited to the above, for example, the number of the water outlets 30 may be changed to two, and the two water outlets 30 are respectively disposed at the ends of the two water outlet guide channels 42 to improve the efficiency of the cooling liquid 100 flowing out from the water outlets 30 to the outside. In addition, the number of the water outlet guide strips is not limited to three, and may be changed to one according to the design.
In one embodiment of the present invention, two water inlet guide strips 50 are connected to the inner wall 15 of the cylindrical housing shell 10, and the two water inlet guide strips 50 form a water inlet guide channel 51 extending in the longitudinal direction in the annular housing space 11. The inlet water guide passage 51 extends straight in the longitudinal direction F toward the opening 13. The water inlet guide passage 51 communicates with the water inlet 20. The water inlet guide passage 51 is used to guide the coolant 100 flowing in from the water inlet 20 to the bottom of the annular accommodating space 11. The two water inlet guide strips 50 are connected to the two water outlet guide strips 40, respectively. In addition, the number of the water inlet guide bars is not limited to two, and may be changed to one according to the design.
In an embodiment of the present invention, the upper cover 60 covers the cylindrical housing case 10. The upper cover 60 and the cylindrical receiving case 10 are coupled to each other in an integrally formed manner. The cylindrical housing case 10 and its annular housing space 11, the outer wall 14, the inner wall 15, the three water outlet guide strips 40, 40a, the two water inlet guide strips 50 and the upper cover 60 are formed by a casting process, which can save the time and cost for separately manufacturing and welding the water flow passage and the upper cover 60 and the cylindrical housing case 10, and also form a water channel for guiding the cooling liquid 100 by adding a large capacity of the annular housing space 11 to the cylindrical housing case 10.
As shown in fig. 1, 2 and 4, when a user wants to use the cooling device 1 of the present invention to cool the motor main body 210, first, the user needs to put the cylindrical housing case 10 around the motor main body 210. Then, the user should inject the cooling liquid 100 into the annular accommodating space 11 from the water inlet 20, so that the cooling liquid 100 flows to the bottom of the annular accommodating space 11 along the water inlet direction a in the water inlet guide passage 51. When the coolant 100 flows to the bottom of the annular housing space 11, it flows along the bottom wall surface of the annular housing space 11 in the flow direction B, C to the left and right.
As shown in fig. 1, 3 and 4, the cooling liquids 100 flowing along the flow direction B, C converge at the other side of the annular accommodating space 11, and at this time, the converging cooling liquids 100 gradually rise along the rising direction D; in this way, the height of the raised cooling liquid 100 in the annular accommodating space 11 is higher than that of the motor main body 210, so that the motor main body 210 can be completely surrounded and large-area heat exchange can be performed to achieve the purpose of cooling the motor 200.
As shown in fig. 2, 3 and 5, in the process that the merged cooling liquid 100 gradually rises along the rising direction D, the cooling liquid 100 absorbs the heat emitted from the motor main body 210 and gradually rises in temperature; when the coolant 100 rises to the water outlet guide opening 41, the coolant 100 flows into the water outlet guide passage 42 and flows out from the water outlet 30 to the outside in the water outlet direction E. Therefore, by the above-mentioned water channel design, the temperature of the target hot zone (i.e. the location of the motor body 210) can be effectively removed, and the water with higher temperature rises to a high position and then effectively flows out to the outside through the water outlet guide water channel 42.
By the design of the motor 200 of the present invention, a large area cooling effect can be achieved, and the motor 200 can achieve an energy saving effect without additional power supply. In addition, the water channel design of the motor 200 can effectively remove the temperature of the target hot zone, and allow the water with higher temperature to rise to a high position and then effectively flow out to the outside. The motor 200 is formed by a casting process, which can save time and cost for separately manufacturing and welding the water flow passage and the upper cover and the cylindrical receiving case.
The utility model shows the characteristics of the prior art with respect to the purpose, means and efficacy. It should be noted that the above-mentioned embodiments are merely examples for convenience of description, and the scope of the present invention is not limited to the above-mentioned embodiments but only by the appended claims.
